What is the total power consumed in a parallel circuit with a source voltage of 12,500 volts and a total current of 4 amperes?

To find the total power consumed in a parallel circuit, you can use the formula for power, which is the product of voltage and current:

Power (P) = Voltage (V) × Current (I).

In this case, the source voltage is 12,500 volts and the total current is 4 amperes. Plugging these values into the formula gives:

P = 12,500 V × 4 A = 50,000 W.

Thus, the total power consumed in the circuit is indeed 50,000 watts. This aligns with the correct answer choice, showcasing a fundamental principle in electrical circuits: the power consumed is directly related to both the voltage across the circuit and the total current flowing through it. Understanding this relationship is crucial for working with electrical systems, especially when dealing with parallel configurations where the voltage remains constant while current may vary.
